针对小卫星动平衡问题;从小卫星姿态精度角度分析卫星动平衡的必要性,并提出配重优化方法、首先进行理论和仿真分析,表明质心偏移降低星体姿态精度、增加姿控能源和工质消耗、并导致姿态确定和控制器设计参数产生偏差;从而导致卫星姿态产生系统误差;因而动平衡是提高卫星服役质量和服役寿命的必要步骤。然后提出配重优化的动态规划法和单纯形法优化模型,并给出程序设计以及计算实例。
In order to solve the problem of dynamic balance of small satellites, the necessity of dynamic balance of satellites is analyzed from the attitude accuracy of small satellites. The optimization method of counterweight is proposed. Theoretical and simulation analyzes are carried out first, showing that the center of mass offset reduces the attitude accuracy of the stars and increases the attitude control energy and working fluid Resulting in the deviation of the attitude determination and the design parameters of the controller. As a result, the satellite attitude produces systematic errors. Therefore, dynamic balancing is a necessary step to improve the service quality and service life of the satellite. Then, the dynamic programming method and the simplex method optimization model of weight optimization are proposed, and the program design and calculation examples are given.
